Continuation will describe in detail the operation of compressor 10 referring to figs. 1 through Fig. 3.At the run duration of compressor 10, can supply power to motor sub-assembly 18, make rotor 62 rotation and rotating driveshafts 64, this makes again moving vortex 70 detour with respect to deciding vortex 72.Moving vortex 70 produces negative pressure with respect to the motion of detouring of deciding vortex 72 at suction port 89 places, and this makes fluid be sucked in compressor 10 and enter in the first portion 104 of suction passage 100 from the outside of frame set 12 by sucking accessory 28.
Be in directly to attract the position at suction passage 100 and put (Fig. 1), fluid can flow directly into second portion 106 from first portion 104, then flows directly into third part 108, and the fluid pockets chamber that then flows directly at moving vortex 70 and decide to form between vortex 72.Second portion 106 is put and can roughly be sealed for first portion 104 and third part 108 directly attracting the position, thereby, second portion 106 be in directly attract the position flow the fluid that passes suction passage 100 when putting can be roughly isolated with intake chamber 41.In this way, the fluid of suction compressing mechanism 20 will absorb relatively few heat from motor sub-assembly 18 and/or other parts that be arranged in intake chamber 41.Because described fluid is that in compressing mechanism 20, compression before can be because these parts be heated, so described fluid is being discharged from Shi Buhui heat as originally by outlet fitting 24.In this way, the system that includes compressor 10 can more effectively move.
The long-play of motor sub-assembly 18 and/or the operation of motor sub-assembly 18 under high load condition are with the temperature of rising motor sub-assembly 18.Within actuator 102 can be arranged on the roughly near field scope of motor sub-assembly 18, make the heat from motor sub-assembly 18 can be passed to by the mode of convection current reed member 132.
As mentioned above, reed member 132 can the bending in response to the rising of the temperature in intake chamber 41.Because the third part 108 of suction passage 100 is fixing with respect to deciding vortex 72, so when reed member 132 is crooked in response to the temperature in intake chamber 41 raises, the first end 140 of reed member 132 can be outwardly-bent with respect to first portion 104 and third part 108 towards housing 32, thereby make second portion 106 put (Fig. 1) and be switched to motor cool position (Fig. 3) or to directly attracting the position any position (for example neutral position shown in Figure 2) of putting between (Fig. 1) and motor cool position (Fig. 3) from directly attracting the position around hinge 130.
When second portion 106 was put towards the neutral position pivotable from directly attracting the position, the first end 118 of second portion 106 separated with the end 114 of first portion 104, and the second end 120 of second portion 106 separates with the end 128 of third part 108.Thereby when second portion 106 mediates, first portion's fluid in first portion 104 can flow out suction passage 100 and flow into intake chamber 41, and the second portion fluid in first portion 104 can directly flow into, and second portion 106 is also directly mobile to be passed third part 108 and flow into compressing mechanism 20.Endways 114 and the first end 118 of second portion 106 between leave first portion's fluid of suction passage 100 can be by deflector 122 towards the base 38 of frame set 12, around motor sub-assembly 18 and guiding downwards.The fluid that flows into intake chambers 41 from first portion 104 can be in relatively low temperature, and can in endways 128 and the second end 120 of second portion 106 between upwards sucked back to the third part 108 that enters suction passage 100 before from motor sub-assembly 18 absorption heats.In this way, in the neutral position, the first portion fluid flows into intake chamber 41 with cooling motor assembly 18, and the second portion fluid can roughly flow directly into compressing mechanism 20 and hardly or not the parts from intake chamber 41 absorb heat.
The amount of bow of reed member 132 makes the bending of reed member 132 increase along with the rising of the temperature around reed member 132 based on the temperature around reed member 132.Thereby as long as the temperature of motor sub-assembly 18 continues to rise, actuator 102 will make the second portion 106 of suction passage 100 towards the motor cool position pivotable shown in Fig. 3 constantly.In the motor cool position, all in first portion 104 or roughly all fluid enter in third part 108 and can flow out suction passage 100 before in compressing mechanism 20 with around intake chamber 41 circulation and cooling motor assemblies 18 sucked back.
